Water damage and mould are increasing concerns for many Australian buildings, particularly due to issues with construction, compliance, and environmental factors. In this blog post, we explore why so many buildings are dealing with water ingress, mould, and structural damage, drawing on real-world findings from inspections performed at various properties.

Common Causes of Building Leaks

Roofing Defects

Roofing defects like misaligned shingles, broken tiles, and deteriorating seals are some of the primary culprits for building leaks. A roof serves as the first line of defense against water entering a building, and any flaws or gaps in the roofing system can lead to moisture seeping into the structure. Inadequate roofing systems are particularly prone to damage during heavy rain, leading to persistent leaks and significant water damage.

Faulty Plumbing

Plumbing issues are another widespread cause of water damage. These problems may stem from burst pipes, faulty seals, corroded fittings, or leaks hidden within the walls or floors of a building. In some cases, leaks may not be immediately visible, leading to long-term damage that can compromise the structural integrity of the property. Furthermore, faulty plumbing often results in high water bills and wasted resources.

Failed Doors and Windows

Doors and windows are essential for providing natural light and ventilation. However, if they are improperly installed or if their seals fail, they become weak points for water ingress. When water penetrates through these weak points, it can accumulate in the walls or floors, leading to long-term structural damage, mould growth, and even wood rot. Regular maintenance and proper installation are critical for ensuring these entry points remain waterproof.

Inadequate Water Management and Drainage Systems

Water management systems, including drainage plans, play a vital role in protecting buildings from water damage. Improper or poorly designed drainage systems can cause water to pool near the foundation of a property. Over time, this water may seep into the walls and floors, resulting in moisture buildup, water damage, and the growth of mould and mildew.

Slab Heave and Rising Damp

Water infiltration also occurs through more insidious means, such as slab heave and rising damp. Slab heave is when reactive clay soils beneath a foundation expand and contract with moisture, causing structural movement and cracks that lead to leaks. Rising damp is the vertical movement of moisture through porous building materials like brick and concrete. These issues are particularly problematic for properties with poor foundation protection, and they can result in extensive and costly damage.

Efflorescence: The Warning Sign

Efflorescence is a telltale sign that moisture is accumulating within the building. It refers to the white, powdery deposits left behind by water as it evaporates from building surfaces. Efflorescence is a visual cue that moisture problems exist and should be addressed promptly to prevent structural damage.

Compliance Issues and NCC Breaches

In many cases, water damage is a result of non-compliance with Australia's National Construction Code (NCC). Breaches in building compliance, such as the use of improper materials or failure to meet waterproofing standards, can leave a building vulnerable to water ingress. Failing to comply with the NCC increases the likelihood of moisture buildup and subsequent structural problems.

The Importance of Waterproofing

One of the most effective ways to protect a building from water ingress is by ensuring that it has proper waterproofing. Failed waterproofing in areas like balconies, bathrooms, and basements can lead to significant leaks. In multi-story buildings, a failed waterproofing system on an upper floor can have a cascading effect, causing damage to the floors below.

Inspection Summary Example: Findings from a Recent Investigation

In a recent inspection performed at North Tower, Main Tower, and the Basement Carpark, several compliance and defect issues were identified:

• Basement Carpark and Common Areas: Non-compliant waterproofing was found, leading to severe water migration below tiles and into the carpark. The lack of proper drainage in outdoor areas also contributed to water damage and mould in Unit 6.

• Unit 6: The grassed area outside the unit lacked drainage, causing water damage and mould in the bedroom.

• Unit 18: Water ingress during heavy rains was observed due to issues with a structural pillar and a rooftop pool area in a neighboring unit.

• Unit 22: Water ingress directly beneath the rooftop pool was identified, with widespread calcification and water damage in the pool deck's substrate framing.
